Striker Book 3 DS 9 Tac Missiles Installment 4

[snrdg082102]

To ensure I'm on the right track with Tac Missile design here is what I have for a TL 9 11 cm HE tac missile.

1. Warhead: TL 9 HE weight: 1.75 kg, volume: 0.00175 m^3, price: Cr14

2. Guidance: Operator guided Radio link
A. Warhead guidance package: weight: 2 kg, volume: .002 m^3, price: Cr200
B. Launcher guidance package: weight: 20 kg, volume: .02 m^3, price: Cr2000
C. 5 power radio:, weight: .1 kg, volume: .0002 m^3, price: Cr75

3. Rail Launcher: weight: 1.75 kg, volume: 0.00175 m^3, price: Cr87.5

4. Propellant: 5 power radio has a maximum range of 5 km.
A. Warhead and guidance combined weight = 1.75 + 2 + 0.1 = 3.85 kg
B. Propellant weight multiplier is 3 + 0.1 for being over 4 km.
C. Required propellant weight: 3.85 kg x 3.1 = 11.935 kg
D. Propellant data: weight: 11.935 kg, volume: .011935 m^3, price: Cr11.935

Missile Statistics:
A. Weight: 1.75 + 2 + 0.1 + 11. 935 = 15.785 kg
B. Volume: .00175 + 0.002 + 0.0002 + 0.011935 = 0.015885 m^3
C. Price: 14 + 200 + 75 + 11.935 = Cr300.935

Launcher Statistics:
A. Weight: 1.75 + 20 + 0.1 = 21.85 kg
B. Volume: .00175 + 0.02 + .0002 = 0.02195 m^3
C. Price: 87.5 + 2000 + 75 = Cr2162.5

Total System:
A. Weight: 15.785 + 21.85 = 37.635 kg
B. Volume: .0.015885 + 0.02195 = 0.0237 m^3
C. Price: 300.935 +2162.5 = Cr2463.435

Hopefully my numbers are right too.

Nope, the numbers where a bit off, hopefully my corrections are right, (I'm keeping my fingers crossed):
Revised calculations changed volume and cost. Radio volume was miss calculated

To ensure I'm on the right track with Tac Missile design here is what I have for a TL 9 11 cm HE tac missile.

1. Warhead: TL 9 HE weight: 1.75 kg, volume: 0.00175 m^3, price: Cr14.

Per the design sequence, "the cost multiplier is 4." HE Warhead costs 4*1.75=Cr7.

2. Guidance: Operator guided Radio link
A. Warhead guidance package: weight: 2 kg, volume: .002 m^3, price: Cr200
B. Launcher guidance package: weight: 20 kg, volume: .02 m^3, price: Cr2000
C. 5 power radio:, weight: .1 kg, volume: .0004 m^3, price: Cr75.

While evaluating your design, I realized my own spreadsheet lacked a radio for the missile. Whups!

3. Rail Launcher: weight: 1.75 kg, volume: 0.00175 m^3, price: Cr87.5

Per the design sequence, "Each launch rail weighs the same as one missile," so 15.785 kg.

4. Propellant: 5 power radio has a maximum range of 5 km.
A. Warhead and guidance combined weight = 1.75 + 2 + 0.1 = 3.85 kg
B. Propellant weight multiplier is 3 + 0.1 for being over 4 km.
C. Required propellant weight: 3.85 kg x 3.1 = 11.935 kg
D. Propellant data: weight: 11.935 kg, volume: .011935 m^3, price: Cr11.935

Missile Statistics:
A. Weight: 1.75 + 2 + 0.1 + 11. 935 = 15.785 kg
B. Volume: .00175 + 0.002 + 0.0004 + 0.011935 = 0.0161 m^3

I think the radio's volume is too high.

C. Price: 14 + 200 + 75 + 11.935 = Cr300.935

See note on warhead price.

Launcher Statistics:
A. Weight: 1.75 + 20 + 0.1 = 21.85 kg
B. Volume: .00175 + 0.02 + .0004 = .0042 m^3
C. Price: 87.5 + 2000 + 75 = Cr2162.5

See note on rail mass.

You might also consider calculating the maintenance cost, in case you decide to play with that rule. It's amazing how much maintenance impacts high tech.

Hello Carlobrand,

Thanks for checking and catching my errors. My process appears to be correct my math, on the other hand, is out to lunch.

Per the design sequence, "the cost multiplier is 4." HE Warhead costs 4*1.75=Cr7.

Oops, my bad and thanks for catching my error.

When I was trying to print out the section of my spreadsheet that summed up the tac missile calculation there was a print error.

I selected print and walked out to the kitchen for another cup of coffee and didn't find the document, but there was an indication of a print error.
While troubleshooting I canceled the page I was working on and discovered that the printer was out of paper.

Had I waited for the printing to complete I would have known that I was out of paper.

Going back to the page I clicked on edit page thinking I was still on the new page.

Today must be Monday.

My apologies to everyone for my confusion and here is the original data that I posted.

Hello again Carlobrand and thanks again for checking my revised calculations.

Per the design sequence, "the cost multiplier is 4." HE Warhead costs 4*1.75=Cr7.

Yep, my cost was off since my formula had times 2 in addition to the times 4.

While evaluating your design, I realized my own spreadsheet lacked a radio for the missile. Whups!

You shouldn't leave your spreadsheet out where thieves can steal the radio.

Per the design sequence, "Each launch rail weighs the same as one missile," so 15.785 kg.

Another good catch what happened here is that when I was building my spreadsheet I followed the order of warhead, launchers, guidance, and propellant. I never went back and included the guidance and propellant. I've fixed the issue.

I think the radio's volume is too high.

Could be here is how I calculated the volumes:

Per D9 A. Tac missile volume = component weight ÷ 1000

Warhead Radio guidance assembly = 2 kg ÷ 1000 = .002
Launcher Radio guidance assembly = 20 kg ÷ 1000 = .02

Radio Table Book 3 page 42: Volume = radio weight ÷ 500
TL 9 Radio weight 0.1 kg

0.1 ÷ 500 = .0002 m^3

Total Warhead Radio guidance package = .002 + .0002 = .0022 m^3
Total Launcher Radio Guidance package = .02 + .0002 = .0202 m^3

See note on warhead price.


See note on rail mass.

You might also consider calculating the maintenance cost, in case you decide to play with that rule. It's amazing how much maintenance impacts high tech.

Since both warhead price and rail mass are off the totals are going to be out to lunch too.

I have to get the design sequence down first, math included, before I branch out to stuff like maintenance cost.

Being a submarine sonar tech I have a little idea on how maintenance adds up the cost of a system. One of the jobs I had was ordering the repair parts for sonar equipment. I didn't last too long since I didn't like spending money that the division's budget didn't have or waking people up to run a chit ordering the parts.

Did I do better on this one Calrobrand?

 

[Carlobrand]

You shouldn't leave your spreadsheet out where thieves can steal the radio.

Maybe my kid borrowed it for a school project. He's in an engineering magnet school.

Looks right.

Check his back pack the next time something goes missing

Looks right.

Great news for me since both the process and the math appear to show I've got a handle on the system.

Thanks for the review and help Carlobrand.
